You want to be sure that you get creative with your poll questions. It can be very boring for everyone involved if you always ask the same question with the same answers. Mix it up a little bit to encourage fans to actually participate.
It is also important to know that there is such thing as overusing polls. You want your audience to feel like they are being engaged not being used as a focus group. Stick to doing polls no more than once a week.
